How to speed up the start of `mix test`?

Yes, I’ve used the latest version,

$ asdf list elixir
  1.12.3-otp-24
  ref:v1.12.3
$ asdf list erlang
  24.0.6

and I found this answer: `mix` even more slugish with Elixir 1.12.1

Maybe this problem is not easy to solve, looking forward to the arrival of Elixir 1.13 version.
